0x0 error

Question

0xo error cannot get into windows insider program. How to I fix it

Answer 1

Hello Robert, 

What is status of "Windows Insider Service"?

• Click Windows logo and type services
• Scroll down to Windows Insider Service
• It should be set manual.

By disabling this service I could re-create that 0x0 error, changing that service back to manual I could link that PC to Insider program without errors.

One way you can try is to download latest insider preview ISO, mount it (double click or right click, select mount) and run setup.exe on created virtual CD/DVD drive to start in-place update.

You can download ISO from here:

https://www.microsoft.com/en-us/software-download/windowsinsiderpreviewiso

If that page doesn't open correctly then click browser refresh button.

If something goes wrong then system may automatic restore to previous version or you have 10 days window to launch "Restore to previous version".

Just in case it would be good idea to take disk image of your currently installed system to external  USB disk. If later on insider program you encounter some serious issues and your only option to get out of program is clean install then this disk image save you lot of time to get back on track with released version.

For making disk image (and USB recovery tool!!!) you can use free Macrium Reflect.

Note also that since v2004 (or 20H2) WIP page show this message instead of "Get Started" button if optional diagnostic data  isn't set on. So settings must be correct before you have button to start  join insider program.

As we noted with Johnny on another thread, this last paragraph is quite confusing. It would be better to understand if it start with "If you turn off optional ...", but it would be better without that paragraph.

Answer 3

Make sure your Diagnostics are set to Full.

Hi CK,

"Optional" as of last spring, best to list both:

As part of this change, any device that was previously set to Enhanced will be defaulted to Basic.  This will result in some devices not receiving flights as expected.  Enabling Optional Diagnostic Data will set the device to diagnostic level 3 (formerly Full) and return users to flighting as expected

Regards,

"As far as the 0x0 error, if not mistaken, does that not come up with not using an email address or account that is already registered for the Insider program."

To my understanding this 0x0 error appear immediately after pressing 'Get started' button before e-mail address is asked and that could indicate that there is something wrong in OS itself.

Perhaps OP could tell when he get this error message.

Not positive as have only come across this once, deleting the SelfHost key corrected this. From 10 Forums:

Check the date and time in Taskbar.

What Anti-virus are you using. Anything other than Windows Defender, disable, better to remove it.

Put the following in a batch file then run from a Elevated Command Prompt:

@echo off

date /t & time /t

echo Dism /Online /Cleanup-Image /StartComponentCleanup

Dism /Online /Cleanup-Image /StartComponentCleanup

echo ...

date /t & time /t

echo Dism /Online /Cleanup-Image /RestoreHealth

Dism /Online /Cleanup-Image /RestoreHealth

echo ...

date /t & time /t

echo SFC /scannow

SFC /scannow

date /t & time /t

or you can run each command individually in a Elevated Command Prompt.

Reboot then try joining the Insider Program again. If still no joy then do a Clean Boot and try it again.

Regards,

This made me chuckle, because back when this

did change you guys all used "full" and I used

"optional" and never corrected anyone.

Hehehe, it takes us old guys longer to adapt  :-)

I had simply forgot about the conversation Pauli and I had till he reposted. Changed my diagnostic setting on my main, and it displays the warning screen that Pauli shows in his example of no Get Started button. Switching back to Optional brings back the button.

Think we all have to thank MS for fixing that as this did come up often. One less thing for us to worry about.

As far as the 0x0 error, if not mistaken, does that not come up with not using an email address or account that is already registered for the Insider program. Normally deleting the SelfHost key fixes. Is the OP using a different account or email address that he used to register for the program. Understand MS has simplified the sign-in process. It should all display on using Get Started.

Suggest at this point, the OP follow Pauli's advice and do an in-place upgrade of current Dev ISO. This would automatically put him in Insider. He would also have to check Insider page Setting as it tends to default to Beta channel rather than Dev channel.

And please make an image backup of your current setup, in case you want to revert back.

Regards CK, Sorry  :-)
